I applied a topical cortisone cream to my face that was suggested by my pharmacist. I only used it a couple of times. The cream was meant to clear up some eczema patches on my cheeks and around my jawline. I have used SPF 60 to protect from the sun, however I have lost the pigmentation in my skin. Is there a cure for this? How can I prevent it from getting worse? ( I have discontinued the use of the cream)
